Ruling on making phone apps for some educational projects and selling them

Question

Is it permissible to make phone apps to sell Islamic information? For example, the iPhone mobile phone has a number of apps that are sold via the Apple company, such as the electronic Mushaf, Saheeh al-Bukhaari, Saheeh Muslim, and so on. I would like to make apps like these, that deal with the Qur’an and Prophet’s hadeeths, for the iPhone and iPad, and upload them to the App Store as unique apps.

Striving to spread knowledge and the Qur’an is a great good
deed, and making use of modern technology to do that is one of the best and
greatest good deeds, if a person does it seeking to please Allah, especially
nowadays when followers of whims and desires and the people of kufr,
hypocrisy and division are hastening to spread evil, immorality, shirk and
kufr, and everything that angers Allah, may He be exalted, via electronic
means by using the highest levels of modern technology that mankind has
attained.

Making these Islamic apps that contain nothing that is
contrary to the teaching of Islam, rather they are aimed at spreading the
religion of Allah, and teaching Qur’an and hadeeth, is a great and blessed
good deed, if you do it sincerely for the sake of Allah and with the right
intention, whilst striving to do your work well and referring it to a
committee of specialists in the field in which you are making the app
(Qur’an, hadeeth, and so on), for them to check it from an academic point of
view and to make sure that it is free of errors.

There is also nothing wrong with you selling it to people via
this electronic seller (the App Store).
